Abstract

A compressible anti extrusion packing (10) for sealing valve stems shafts and rods having an interbraided round braided or square braided outer layer (14) disposed over a densified interbraided round braided or square braided core (12). In certain embodiments the compressible packing (10) includes a metal jacketed (22) flexible graphite yarn (20) interbraided as a core (12) and an interbraided outer layer (14) made of flexible graphite yarn (16) with a carbon carrier (24). In one embodiment the metal jacket (22) is a knitted metal jacket. The core (12) is densified by mechanical compression to control density and size.
